The DC mode overrides all other operating modes. OPERATING REFRIGERATOR AT HIGH The refrigerator controls will work down to 9.6 VDC. ALTITUDE All gas appliances experience lowered efficiency (or rat- ing) at high altitude This is a direct result of lower atmos- pheric pressure and oxygen levels, and is not a defect of the refrigerator. Reduced cooling performance and burner outage may occur at altitudes higher than 5500 feet above sea level (while operating on LP gas). Always operate refrigerator on electric power at altitudes higher than 5500 feet.
PURGING AIR FROM THE LINES If the refrigerator has not been used for a long time - or - the LP tanks have just been refilled, air may be trapped in the supply lines. To purge the air from the lines, turn the refrigerator off and on by pressing the ON/OFF button. If the flame is not lit within 45 seconds, turn the refrigerator off and back on again. This procedure can be repeated 3 to 4 times. If repeated attempts fail to start the LP gas opera- tion, check to make sure that the LP gas supply tanks are not empty and that all manual shutoff valves in the lines are open. If the problem persists, turn the refrigerator off and take it to a Service Center.

This refrigerator is intended for continuous use. Do not allow it to run unattended when there is a risk for loss of electricity or fuel. Food spoilage could occur.
The refrigerator’s control system still consumes a few milliamps even if it is turned off. If your RV is being put into winter storage, it is recommended to either put your RV batteries on a battery charger or turn off the vehicle’s main 12 VDC switch. This will prevent the RV battery from discharging.
